Kitplane Engines - Lycoming IO-233

The next Kitplane engine highlighted here is the brand new Lycoming IO-233 / O-233 built specifically for the LSA and Kitplane market.  The IO-233 is a four cylinder, air-cooled, horizontally-opposed piston aircraft engine that produces between 100 hp (2400 RPM) and 116 hp (2800 RPM).  This engine is a modernized version of the previous Lycoming O-235 with engineered weight reduction and modern engine ignition technology.  The new design features include the incorporation of throttle body fuel injection with an optimized air induction system and dual electronic ignition, or optionally a carburetor in place of the throttle body injector to save further cost and weight.  There is substantial overall weight reductions and improvements in engine size to target the IO-233-LSA for today's Light Sport Aircraft market. The engine is also approved for 2,400 hour time between overhaul (TBO) intervals giving it one of the longest Light Sport Engine TBOs in the market today.  To offer pilots fuel options, this engine is approved for the use of 100LL or 93 AKI automotive (MOGAS) based fuels that conform to Lycoming specifications.

The initial standard version of the Lycoming 233 series engine is carbureted. Lycoming continues to incorporate input from pilots and manufacturers all over the world, which will result in both carbureted and injected configurations of the product.  Here is a very sharp looking Kitfox Super Sport with a Lycoming O-233 (carbureted version) installed -
